The door lock actuators described above are an electric motor hooked to a lead screw and/or reduction gears (
like this). The solenoid actuators (like the ones Alan linked) don't have motors inside.

We've argued about this definition in the past. My impression is that a solenoid actuator necessarily implies a proper solenoid (i.e. an energized coil that produces a substantially uniform magnetic field in the space along the length of its internal axis, with a plunger that moves along that axis, through that space, as a result of the electrical current supplied to the coil); others have suggested that a less restrictive definition satisfies the rule. In my opinion, a conventional electric bell is not a solenoid actuator.
